Income Tax Disclosure [Abstract]
Income Taxes	On an interim basis, the Company estimates what its anticipated annual effective tax rate will be and records a quarterly income tax provision in accordance with the estimated annual rate, plus the tax effect of certain discrete items that arise during the quarter. As the fiscal year progresses, the Company refines its estimates based on actual events and financial results during the year. This process can result in significant changes to the Company's estimated effective tax rate. When this occurs, the income tax provision is adjusted during the quarter in which the estimates are refined so that the year-to-date provision reflects the estimated annual effective tax rate. These changes, along with adjustments to the Company's deferred taxes and related valuation allowance, may create fluctuations in the overall effective tax rate from quarter to quarter. The Company’s effective tax rate for the three and six months ended June 30, 2015 differed from the U.S. federal statutory rate primarily due to unrecognized tax benefits, state income taxes and permanent non-deductible tax items. The total amount of unrecognized tax benefits, excluding associated interest and penalties, was $0.6 million as of June 30, 2015, of which $0.1 million would impact the effective tax rate if recognized. The total balance of accrued interest and penalties related to state uncertain tax positions was $14,000 and $28,000 as of June 30, 2015 and December 31, 2014, respectively. The Company recognizes interest and penalties related to state uncertain tax positions as a component of income tax expense, and the accrued interest and penalties are included in deferred and other long-term liabilities in the Company’s condensed consolidated balance sheets. There were no material interest or penalties included in income tax expense for the three and six months ended June 30, 2015 and June 30, 2014.
